Isn't ensure necessary? Because http://clojure.org/refs says that - "No changes will have been made by any other transactions to any Refs that have been ref-set/altered/ensured by this transaction." It doesn't guarantee that a ref 'r' will not change if we have (dosync (..bunch of stuff not involving r..) @r (..bunch of stuff not involving r..)). So shouldn't we have to do - (defn report-status [] (apply println (dosync [(ensure my-hash) (ensure new-keys)]))) - Thanx -- You received this message because you are subscribed to the Google Groups "Clojure" group.
